Title: Code conversion system for multi-value picture
Inventor: OGASAWARA HIROMICHI
IPC: H04N1/41
Filed: 1990-09-12
Abstract: PURPOSE:To implement facsimile communication for multi-value picture information with an almost similar transmission efficiency to that for binary picture information by converting the multi-value picture information including an intermediate tone into a run length of a gradation changing picture element number, compressing the quantity of information by the MH or MR coding system and sending the compressed information. CONSTITUTION:An original 1 is converted into an electric analog signal at a read section 2, converted into a digital multi-value picture signal in the unit of picture elements by a signal converter 3 and transferred to a run length converter 4 synchronously with a transfer clock. The multi-value picture signal (b) and a multi-value picture signal (a) resulting from the multi-value picture signal (b) delayed by a delay circuit 11 are compared by a comparator 12, from which a ¦b-a¦ gradation change number signal 15 and a + or - detection signal 14 required for a code converter 5 are generated. Moreover, the converter 5 detects the number of picture elements of the same gradation, a changed gradation number and the polarity of the changed gradation from the converter 4 and applies a linear (MH) coding or a 2-dimension (MR) coding to the picture signal. The MH/MR coding system for redundancy compression is used effectively for the multi-value picture signal similarly in the case with the processing of a binary picture signal because the multi-value picture signal information has a higher redundancy in 2-dimension compression.

IPC: F04D19/04
Filed: 1984-11-19
Abstract: PURPOSE:To increase pressure ratio and exhaust volume by making the capacity of molecular pumps and the blade angle of disks bigger as they are closer to the air suction side and making both of them smaller as they are closer to the exhaust side. CONSTITUTION:In a high vacuum exhaust equipment having plural stages of molecular pumps 21 and connecting pipes 23, the number of molecular pumps 21 is largest at the side of a suction opening 24 and is getting smaller as they become closer to an exhaust opening 25.

Title: Cutting method for thin-plate material and cut-working method for lead, cut-working apparatus and lead frame
Inventor: KUME SUSUMU
IPC: H01L23/50
Filed: 1992-08-19
Abstract: PURPOSE:To prolong the life time of a cutting blade and manufacture a metallic mold easily, by suppressing the generation of burr even when the material thickness of the material to be worked is very small, and by performing the cut-working of a high quality. CONSTITUTION:When striking a work 4 with a V-notch punch 7, the space between a die 5 and a compression-sandwiching supporter 6 is set larger than the thickness of the work 4. Thereby, a V-groove is formed through the striking operation caused by the V-notch punch 7, and the work 4 is deflected between the die 5 and the compression-sandwiching supporter 6. Then, the penetrating position of the V-notch punch 7 is so regulated as to be an intermediate position of the thickness of the work 4, and the V-notch punch 7 is stopped in the penetrating position. Subsequently, the work 4 is compression-sandwiched, narrowing the compression-sandwiched space between the die 5 and the compression- sandwiching supporter 6. Thereby, the work 4 is cut with the V-notch punch 7, giving a rotational moment to the work 4 while eliminating the deflection of the work 4.

IPC: H01L29/78
Filed: 1984-11-16
Abstract: PURPOSE:To avoid generation of leak currents between a source and a drain due to a parasitic MOS, when one conducting type source and drain regions and a gate electrode between said regions are surrounded by a reverse conducting type frame region, by expanding one side of the frame to the extended pats of a source electrode, a drain electrode and the gate electrode. CONSTITUTION:The surface of a P<-> type Si layer 13 is covered by an SiO2 film. Impurities are introduced through said film. N<+> type drain and source regions are formed in the layer 13. A drain electrode 5 and a source electrode 6 are deposited and extended on the regions. A gate electrode is positioned on the SiO2 film between the drain and source region. The gate electrode is extended in the direction of the electrodes 5 and 6. Then the drain and source regions are surrounded by a frame shaped P<+> type region 12 as usual. The entire surface is coated by a polyimide resin. At this time, one side of the region 12 is expanded in the direction of the extended electrodes 5 and 7. Therefore yield of inverted layer due to the charging of the resin is prevented. Thus an MOSFET element 11, which is not erroneously operated, is obtained.
